it's a good idea though, but sometimes maybe some people need to go to work or has job need to be done, and then they quit and work on their job, or maybe take care of their kids, who knows???
so sometimes they really have things need to be done, of course, sometimes people quit because they had a bad score, but again, who knows???
that's the problem, so the main thing is when they quit the game, if they quit the game in the first 3 holes, that might because they had a bad score, if they quit the game with -3 after 4 holes, do you think they will quit the game? again, who knows???
It's a good suggestion, maybe we can add why they left the game and tell everyone who are still playing.
